Weather – here on Earth

I thought I’d blog about weather today, firstly because it often matters when writing about the past, and secondly as a kind of shameless advert for my most recent Alexa skill. Let’s get that out of the way first – it’s called Cumbrian Weather, and it requests a short-range forecast from the Mountain Weather Information Service. Why not just use the built-in weather service on Alexa? Well, MWIS focus on weather insofar as it impacts outdoor pursuits such as walking, cycling, rock-climbing and so on. So the forecast includes essential things like whether the peaks are covered in cloud, what the temperature is at 750m, what height you reach freezing point as you climb up, and the like. All of which interest me, so I have accessed this data-feed and present it through Alexa. Like all my Alexa skills to date, it is entirely free to enable and use.

Which brings me nicely to the impact of weather on historical fiction. You get macro-level events that shape the whole story, such as drought, floods, a long winter, and so on. These are often used to set the scene, or the tone, for a book. Storms at sea are a staple of maritime fiction, and are a handy device for placing characters in unforeseen circumstances.

But in daily life as well as fiction, it’s also the smaller scale events that can derail the best intentions. And the nature of these events varies hugely with location. In London, where I am writing this, then the impact is often seen on transport – the famous autumnal “leaves on the track” problem which no doubt will be affecting commuters before long. A century or so ago, pollution and fog could easily combine to produce an unpleasant, unhealthy, and all-but-impenetrable smog.

Up in Cumbria, a night’s rain in the wrong place can end with localised floods. Storm Desmond, back in the winter of 2015, left major roads unusable, and washed away several bridges, quite apart from the impact on houses and shops. That aside, you can have a run of several days when even low peaks and ridges are invisible because of low cloud, frustrating work and movement between valleys. The various mountain rescue teams are regularly called out to succour people who have been caught by surprise up a height, and are completely unprepared for a weather change.

These more rapid, more local shifts and switches are every bit as important to fictional characters, as their real life equivalents are to us. Naturally, the particular kinds of weather change that matter to people vary from place to place – one location may have low cloud and mist, another one sudden blizzards, and a third sandstorms. It’s as well to find out what your characters might have to contend with!

Next week I’ll be having a quick look at weather on other planets. Not yet an everyday topic for most of us, but potentially it will be in a few years.

Even in the 20th century there were much colder periods – the Swallows and Amazons books describe times when most of the lakes in Cumbria were iced right across. But you’re right, the Thames ice parties sound fantastic 🙂
